Exercise 5.1, 5.2, 5.3 In this exercise the student is asked to first observe the given figure 5.4 from the lab manual and then solve for the FET's Q point. Next, the student began to solve for the transconductance. He used the given equations from the lab manual to calculate the previous steps. Thereafter the student calculated the gain. Common Drain Amplifier Circuit Diagram: The FET Common Drain Amplifier Circuit Diagram shown in Fig. 11-14 has the output voltage developed across the source resistor (R S).The external load (R L) is capacitor-coupled to the source terminal of the FET, and the gate bias voltage (V G) is derived from V DD by means of voltage divider resistors R 1 and R 2.No resistor is connected in series with EE 3101 ELECTRONICS I LABORATORY .

Voltage Title: Microsoft Word - CS_Amp_Guide Author: Chunlong Guo Created Date: 10/29/2003 8:04:45 AM In this lab you will investigate some more sophisticated JFET circuits, such as voltage amplifiers, differential amplifiers, attenuators, and modulators. Before coming to class complete this list of tasks: · Completely read the Lab Write-up · Answer the pre-lab questions utilizing the references and the write-up In common source JFET amplifier there is phase displacement of 180 degrees between the output and input voltage the mid frequency voltage gain of the amplifier is given by A = gm x Rd The voltage gain and phase angular are constant in mid frequency range. JFET Common Drain Amplifier The common Drain amplifier is like common collector configuration of BJT's. Common Drain amplifiers are also known as Buffer circuit. It is called common Drain amplifier. Because Drain terminal is common. The input signal is applied at gate-drain junction and output is taken from source to drain junction. Figure 6. Objectives: 1. Construct and test a voltage amplifier using N-channel JFET device in a common source configuration 2. Apply the voltage divider biasing method to set the DC operating point LAB INSTRUCTIONS Do's Ensure your presence five minutes before the commencement of the lab. Attend all the lab sessions without fail. Come well prepared for every lab session. Complete and Bring the Lab records regularly. Ensure the proper polarity of cables before connecting the kits. Numerical Problem on Common Source amplifier using FET. Example 1: A common source amplifier uses FET having dynamic resistance rd = 120 k-ohm and = 20.
